Abstract
Purpose
Arterial hypotension is frequently observed in critically ill patients. Nitric oxide (NO) is pivotal in vasodilation. We investigated the associations between NO-biomarkers (asymmetrical dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), arginine, and homoarginine) and treatment with norepinephrine and plasma lactate on ICU days 1–3.
Materials and methods
A prospective cohort study of 527 adult ICU patients with NO-biomarkers at admission. Associations with norepinephrine treatment were analyzed in logistic regressions on the first three days of ICU admission. Associations with the highest daily plasma lactate were analyzed with linear mixed models.
Results
Increasing ADMA and arginine were associated with decreased norepinephrine treatment (ICU day 1: OR 0.36 pr 1 μmol/L ADMA, 95 % CI 0.17–0.78; p = 0.009, and OR 0.85 pr 10 μmol/L arginine; 95 % CI 0.79–0.92; p < 0.001). An increase in homoarginine of 1 μmol/L was associated with an increase in plasma lactate of 6 % (95 % CI -2 % to 15 %) from ICU days 1–2 and 4 % (95 % CI -4 % to 13 %) from ICU days 2–3. SDMA was not associated with either outcome.
Conclusions
Increased ADMA and arginine at admission are associated with decreased norepinephrine treatment on the first three days of ICU admission. Increased homoarginine concentrations are associated with increasing plasma lactate.
期刊介绍:
The Journal of Critical Care, the official publication of the World Federation of Societies of Intensive and Critical Care Medicine (WFSICCM), is a leading international, peer-reviewed journal providing original research, review articles, tutorials, and invited articles for physicians and allied health professionals involved in treating the critically ill. The Journal aims to improve patient care by furthering understanding of health systems research and its integration into clinical practice.
The Journal will include articles which discuss:
All aspects of health services research in critical care
System based practice in anesthesiology, perioperative and critical care medicine
The interface between anesthesiology, critical care medicine and pain
Integrating intraoperative management in preparation for postoperative critical care management and recovery
Optimizing patient management, i.e., exploring the interface between evidence-based principles or clinical insight into management and care of complex patients
The team approach in the OR and ICU
System-based research
Medical ethics
Technology in medicine
Seminars discussing current, state of the art, and sometimes controversial topics in anesthesiology, critical care medicine, and professional education
Residency Education.
